Enabling GPRS support

Use PuTTY and SSH to access the clocks in your deployment.
See Using PuTTY.

Create a file named update.sh and insert this content:


#!/bin/sh
 
cp ./clock-setup.json /media/Storage/clock-setup/input
/usr/share/clock-setup/backend/run-clock-setup-foreground.sh
if [ -f /media/Storage/clock-setup/results/UPDATE.PASS  ]; then
    echo "Configuration file accepted "
    exit 1;
fi;
echo "Configuration file rejected"
exit 0 # failed condition

Using PuTTY, navigate to the /etc/ATS/config/ppp_providers.conf file.
Find the line number of your cell provider in the ppp_providers.conf file which you will need to specify in the next step.

Note: Line numbers begin with 0, therefore you must ensure that your count reflects this.
Create a file named clock-setup.json and insert this content. Replace <cell provider> with the number for your cell provider as determined in the previous step.
```
{
    "ATS_CellularEnable":true,
    "ATS_GSMCarrier":<cell provider>
}
```
To update the configuration of one or more clocks with this configuration change, you can use the file update process that is outlined in Configuration updates for the clock. You will have to place the update.sh and clock-setup.json files that you created in previous steps in the script directory as part of the normal file update process.

You will also need to insert the SIM card from your mobile communications provider into each GPRS supported 9000 clock. This will require a 9000 Series clock with a GPRS adapter
